It's important to realize the size of Canada - It's the second largest country in the world, by land mass. Having two months to explore is great, but if you plan to see "all of the important tourist places in Canada" you'll obviously need to leave Toronto. For example, Vancouver, and the west coast of Canada, is a 5-hour plane flight, or a 5-6 day drive. For tours, I would start with a company like Brewster.
